Figure 7. rIL-2 causes expansion of Tregs in vitro.
Naïve primary T-cells were cultured in the absence or presence of ConA for 24 hrs and treated with rIL-2 (60 U/mL). Cell were stained for (A) CD4+/FoxP3+ Tregs and (B) total cell number was calculated. Statistical significance in the data between the different groups has been indicated. (* p < 0.001, + p < 0.01)
